DETAILED DESCRIPTION

Hereinafter, an exemplary embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.

System Configuration

FIG. 1 is a diagram illustrating the overall configuration of an information processing system to which an exemplary embodiment is applied. The information processing system according to the present exemplary embodiment includes a sharedinformation management server100, aprogress control server200, aninput apparatus300, and anoutput apparatus400.

The sharedinformation management server100 is a server that manages information to be shared by a plurality of participants participating in group work. An example of information to be shared, which is the target of management, includes details that each participant learned in advance about the group work. By sharing details that each participant learned in advance with other participants, each participant may implement the group work with common understanding.

Theprogress control server200 is a server that controls and supports the progress of the work of sharing to-be-shared information, which is the target of management performed by the sharedinformation management server100, by participants (the work implemented for sharing information). Various types of work are conceivable as the work of sharing information, such as presentation within the group, distribution of materials, distribution of materials to a terminal of each participant of the group, and displaying of materials on a display device viewable by each participant of the group. In the present exemplary embodiment, an example of presenting details that each participant learned in advance will be described as the sharing work.

Theinput apparatus300 is an apparatus for the participants of the group work to input information to be shared in the group. In the case where to-be-shared information is described in a particular description form, an image processing apparatus may be used as theinput apparatus300. The image processing apparatus includes a so-called scanner apparatus, which optically reads an image on a set document to generate a read image (image data). Exemplary image reading methods include the following: the charge-coupled device (CCD) method of reducing, with the use of a lens, the size of light that is emitted from a light source onto a document and that is reflected from the document, and receiving the size-reduced light with the use of CCDs; and the contact image sensor (CIS) method of receiving, with the use of a CIS, light beams that are sequentially emitted from a light-emitting diode (LED) light source onto a document and that are reflected from the document. An image processing apparatus has a communication function of connecting to the sharedinformation management server100 via a network and transmitting image data of a read description form. In addition, in the case where to-be-shared information is described in a document converted into electronic data (electronic document), an information processing apparatus that transmits the electronic document to the sharedinformation management server100 may be used as theinput apparatus300. Hereinafter, the case in which an image processing apparatus is used as theinput apparatus300 will be described. Therefore, to-be-shared information is sent as image data, which is obtained by reading an image by theinput apparatus300, to the sharedinformation management server100.

Theoutput apparatus400 is an apparatus that outputs presentation information presented for supporting information sharing by the sharedinformation management server100 and theprogress control server200. As theoutput apparatus400, for example, an information processing apparatus including a display device that displays various screens and an input device that receives user operations, such as a personal computer or a smartphone, is used. Outputting of presentation information is performed by, for example, displaying a screen including presentation information on the display device of theoutput apparatus400.

Hardware Configuration of SharedInformation Management Server100 andProgress Control Server200

FIG. 2 is a diagram illustrating an exemplary hardware configuration of the sharedinformation management server100 and theprogress control server200. The sharedinformation management server100 and theprogress control server200 are realized by a computer, which includes a central processing unit (CPU)101, which is an arithmetic processing unit, and random-access memory (RAM)102, read-only memory (ROM)103, and astorage device104, which are storage units. TheRAM102 is a main storage device (main memory), and is used as work memory when theCPU101 performs arithmetic processing. TheROM103 stores programs and data such as prepared setting values. TheCPU101 may directly load programs and data from theROM103 and execute processing. Thestorage device104 is a unit for saving programs and data. Thestorage device104 stores a program, and theCPU101 loads the program stored in thestorage device104 to the main storage device and executes the program. In addition, thestorage device104 stores and saves the result of processing performed by theCPU101. As thestorage device104, for example, a magnetic disk device or a solid state drive (SSD) is used.

In the case where the sharedinformation management server100 and theprogress control server200 are realized by the above-described computer, for example, the individual functions of these servers, which will be described hereinafter, are realized by executing the program by theCPU101. The sharedinformation management server100 and theprogress control server200 are realized as, for example, servers configured on a network. Note that these servers are not limited to configurations with a single piece of hardware (such as a server machine), and may be configured in a distributed manner as a plurality of pieces of hardware or virtual machines. In addition, the functions of the sharedinformation management server100 and the functions of theprogress control server200 may be realized by one server.

Functional Configuration of SharedInformation Management Server100 andProgress Control Server200

FIG. 3 is a diagram illustrating the functional configuration of the sharedinformation management server100 and theprogress control server200. The sharedinformation management server100 includes animage receiving unit110, animage processor120, a documentvector analyzing unit130, a degree-of-similarity analyzing unit140, an analysis-result-presenting-screen generating unit150, and an analysis-result display controller160. Theprogress control server200 includes an information-sharing-time setting unit210, afacilitation determining unit220, a facilitation-information-presenting-screen generating unit230, and a facilitation-information display controller240.

Functions of SharedInformation Management Server100

Theimage receiving unit110 receives, from theinput apparatus300, image data of a description form where to-be-shared information is described (hereinafter referred to as a document image). To-be-shared information is submitted by each participant of the group work. Therefore, theimage receiving unit110 obtains a plurality of documents where to-be-shared information is recorded.

FIG. 10 is a diagram illustrating an example of the configuration of a description form where to-be-shared information is described. By specifying the configuration of adescription form500 to some extent, the load of processing image data of thedescription form500 obtained by theimage receiving unit110 is reduced. In the example illustrated inFIG. 10, thedescription form500 includes adocument field510 and aninformation code520.

Thedocument field510 is provided in a specified area of the space of thedescription form500. A document indicating to-be-shared information is described in thedocument field510. Although it is unnecessary to specify the style and the format of thedocument field510, a document may be explicitly described in blocks such as paragraphs. The following description assumes that a document in thedocument field510 is explicitly described in paragraphs.

Theinformation code520 is a code for recording information regarding the document and information regarding the author of the document. Examples of information regarding the document include the identification information (document ID) of the document, the document creation date and time, the document submission date and time, and the identification information of group work in which the details of the document are used as to-be-shared information. Examples of information regarding the author include the identification information (user ID) of a user who is the author of the document as well as a participant of the group work, and the identification information (group ID) of a group to which the user belongs. In the case where the group work is done in school class or the like, information regarding the author may include the student number of a student who is the user. These items of information may be recorded in theinformation code520 itself, or link information for a server where these items of information are managed may be recorded as theinformation code520. For example, a two-dimensional code or the like is used as theinformation code520.

Referring back toFIG. 3, theimage processor120 processes a document image obtained by theimage receiving unit110. Specifically, theimage processor120 reads theinformation code520 recorded in the document image. On the basis of information read from theinformation code520, for example, the document image is sorted by group which implements group work in which the details of the document are used as to-be-shared information. In addition, theimage processor120 applies optical character recognition (OCR) to the document image to convert the document described in the document image to electronic data. The following processing is performed for each of groups to which documents are sorted.

The documentvector analyzing unit130 performs a document vector analysis of the document (electronic document) obtained by electronic data conversion performed by theimage processor120. Specifically, the documentvector analyzing unit130 divides the electronic document into paragraphs, and calculates a document vector for the description of each paragraph.

The degree-of-similarity analyzing unit140 calculates the degree of similarity in described details in units of paragraphs of the electronic document on the basis of the document vector of each paragraph, which is calculated by the documentvector analyzing unit130. Specifically, the degree-of-similarity analyzing unit140 calculates the degree of similarity of each paragraph in a document with all the paragraphs of all the other documents. This is performed for all the documents. The degree of similarity between paragraphs in the same document is not calculated. In other words, the degree-of-similarity analyzing unit140 calculates the degree of similarity in details in units of paragraphs between different documents, in which the paragraphs are one example of blocks of sentences included in documents.

In addition, the degree-of-similarity analyzing unit140 identifies a combination of paragraphs with the highest degree of similarity between documents, on the basis of the calculated degree of similarity between paragraphs of the individual documents. Specifically, at first, attention is paid to a paragraph of interest in a document of interest, and, among paragraphs of the other documents, a paragraph with the highest degree of similarity with the paragraph of interest is identified in units of documents. This is performed for each paragraph of the document of interest, and further for each document. Accordingly, in units of paragraphs in each document, a paragraph with the highest degree of similarity in each document different from the document including the paragraph is identified. The sharedinformation management server100 and theprogress control server200 regard a combination of paragraphs with the highest degree of similarity between documents as paragraphs describing the same theme, and treat these paragraphs as related paragraphs. For a paragraph of interest in a document of interest, there is a related paragraph in each document different from the document of interest including the paragraph of interest.

The analysis-result-presenting-screen generating unit150 generates an analysis result presenting screen that presents the result of analyzing a document. The analysis-result-presenting-screen generating unit150 generates, as an analysis result presenting screen, a graph indicating related paragraphs of each paragraph in each document on the basis of the relationship between paragraphs with the highest degree of similarity between documents, which is obtained as above. Specifically, the analysis-result-presenting-screen generating unit150 generates a graph in which each paragraph in each document is set as a vertex (node), and a side (edge) is formed between vertices on the basis of the relation based on the degree of similarity between paragraphs. Each side of the graph may be weighted according to the degree of similarity between corresponding paragraphs. The weight added to each side may be represented by, for example, the thickness or length of the side. In addition, the value of the degree of similarity may be displayed at each side. In addition, the vertices of the graph may be rendered in a size corresponding to the size of document vectors calculated in analysis conducted by the documentvector analyzing unit130.

The analysis-result display controller160 transmits an analysis result presenting screen generated by the analysis-result-presenting-screen generating unit150 to theoutput apparatus400, and displays the analysis result presenting screen. The analysis result presenting screen displayed on theoutput apparatus400 is used also as a user interface (UI) screen for receiving an operation performed by a user who is a participant of the group work. The user may operate an input device such as a mouse or a touchscreen to update the graph on the analysis result presenting screen displayed on theoutput apparatus400. For example, each side formed between vertices of the graph may be replaced or vertices may be moved. When each side of the graph is replaced, the analysis-result display controller160 notifies the degree-of-similarity analyzing unit140 of the operation details. The degree-of-similarity analyzing unit140 updates information on the relation between paragraphs in accordance with the received operation details.

Functions ofProgress Control Server200

The information-sharing-time setting unit210 of theprogress control server200 sets work time for performing the work of sharing information by participants of the group work. This setting is performed by, for example, the organizer of the group work. In the case where the group work is done in school class or the like, a teacher may set the work time beforehand. In addition, it is only necessary for the setting of the work time to be done before the operation of the later-describedfacilitation determining unit220 starts.

Thefacilitation determining unit220 determines the target of the sharing work, among combinations of related paragraphs identified by the sharedinformation management server100, and sets the time and the order of performing the sharing work for the combinations of related paragraphs determined as the target of the sharing work. At first, thefacilitation determining unit220 determines related paragraphs that serve as the target of the sharing work. Specifically, attention is paid to a paragraph of interest in a document of interest, and, among related paragraphs of the paragraph of interest, a related paragraph with the lowest degree of similarity is determined as the target of the sharing work regarding the paragraph of interest. This is performed for each paragraph of the document of interest, and further for each document. Accordingly, in units of paragraphs in each document, a related paragraph that serves as the target of the sharing work is determined. Here, a related paragraph with the lowest degree of similarity is determined as the target of the sharing work because a related paragraph with a lower degree of similarity with a paragraph of interest is more likely to contain details that are not described in the paragraph of interest, and it is thus worth doing the sharing work. If a related paragraph has an extremely low degree of similarity, it is more likely that the related paragraph contains no description on the common theme. To this end, a threshold may be set, and, among related paragraphs whose degrees of similarity are higher than the threshold, a related paragraph with the lowest degree of similarity may be determined as the target of the sharing work. Furthermore, in the case where all the related paragraphs of a certain paragraph have very high degrees of similarity and their descriptions contain substantially the same details, it is conceivable that there is little original information in the related paragraphs, and it is thus less worth doing the sharing work. To this end, another threshold different from the above threshold may be set, and, in the case where all the related paragraphs have degrees of similarity that are higher than the threshold, these related paragraphs may be excluded from being the target of the sharing work. Note that the specific method of doing the sharing work is not particularly limited. Mainly, the specific method may be presentation of details described in a related paragraph. The following methods are individually selectable and implementable according to the details of the group work or the attribute of the group: distribution of a document, distribution to the participants' terminals, and displaying on a display device viewable by the participants at the same time.

In addition, thefacilitation determining unit220 allocates, for a related paragraph that serves as the target of the sharing work, work time determined according to the number of characters in the related paragraph. Specifically, for example, in the case where a presentation is performed as the sharing work, a presentation time of one minute per 200 characters may be allocated. The allocated work time may serve as the upper limit. That is, the work may be completed in a time shorter than the allocated time, and, in that case, the work of sharing the next related paragraph may be performed ahead of schedule.

In addition, thefacilitation determining unit220 determines the work order of performing the sharing work for related paragraphs determined as the target of the sharing work. This order is defined as the ascending order of degree of similarity. Thefacilitation determining unit220 compares the cumulative time in the case where the sharing work is performed in the work order and with the work time allocated to each related paragraph and the cumulative time of the entire sharing work set by the information-sharing-time setting unit210, and determines related paragraphs for which the sharing work is to be actually performed so that the cumulative time will fall within the entire work time.

The facilitation-information-presenting-screen generating unit230 generates a facilitation information presenting screen for presenting the above-described facilitation information, which is the result of determination performed by thefacilitation determining unit220. The facilitation information includes the identification information of paragraphs serving as the target of the work, the work order, and the work time for each paragraph. The facilitation-information-presenting-screen generating unit230 generates, for example, a list of identification information and work time of paragraphs, which are arranged in the work order, as a facilitation information presenting screen.

The facilitation-information display controller240 transmits a facilitation information presenting screen generated by the facilitation-information-presenting-screen generating unit230 to theoutput apparatus400, and displays the facilitation information presenting screen. In the case where a facilitation information presenting screen is generated as the above-mentioned list, the facilitation-information display controller240 may display items of related paragraphs in a range in which the cumulative time falls within the entire work time so as to be distinguishable from items of the other related paragraphs. In addition, the facilitation-information display controller240 may display items of related paragraphs for which the sharing work has been completed so as to be distinguishable from items of the other related paragraphs.

Example of Degree-of-Similarity Analysis

FIG. 4 is a diagram illustrating an example of the degree of similarity, in units of paragraphs, calculated by the degree-of-similarity analyzing unit140 of the sharedinformation management server100. In the example illustrated inFIG. 4, the degree of similarity of each paragraph in each document is calculated for five documents including document A to document E. The documents A to E are each composed of three paragraphs. InFIG. 4, attention is paid toparagraphs 1 to 3 of the document A. When attention is paid to the degree of similarity between theparagraph 1 and each paragraph of the document B, the degree of similarity with theparagraph 3 of the document B is 0.98, which is the highest. When attention is paid to the degree of similarity between theparagraph 1 and each paragraph of the document C, the degree of similarity with theparagraph 2 of the document C is 0.99, which is the highest. When attention is paid to the degree of similarity between theparagraph 1 and each paragraph of the document D, the degree of similarity with theparagraph 2 of the document D is 0.88, which is the highest. When attention is paid to the degree of similarity between theparagraph 1 and each paragraph of the document E, the degree of similarity with theparagraph 1 of the document E is 0.63, which is the highest. Therefore, the related paragraphs of theparagraph 1 of the document A are theparagraph 3 of the document B, theparagraph 2 of the document C, theparagraph 2 of the document D, and theparagraph 1 of the document E. Similarly, the related paragraphs of theparagraph 2 of the document A are theparagraph 2 of the document B, theparagraph 1 of the document C, theparagraph 2 of the document D, and theparagraph 2 of the document E. In addition, the related paragraphs of theparagraph 3 of the document A are theparagraph 3 of the document B, theparagraph 3 of the document C, theparagraph 3 of the document D, and theparagraph 2 of the document E.

Furthermore, when attention is paid to theparagraphs 1 to 3 of the document B, the related paragraphs of theparagraph 1 of the document B are theparagraph 1 of the document A, theparagraph 2 of the document C, theparagraph 1 of the document D, and theparagraph 3 of the document E. In addition, the related paragraphs of theparagraph 2 of the document B are theparagraph 1 of the document A, theparagraph 1 of the document C, theparagraph 3 of the document D, and theparagraph 1 of the document E. In addition, the related paragraphs of theparagraph 3 of the document B are theparagraph 3 of the document A, theparagraph 3 of the document C, theparagraph 1 of the document D, and theparagraph 1 of the document E. In this manner, related paragraphs are obtained for each of theparagraphs 1 to 3 of the documents C to E.

Here, the relation between paragraphs is not necessarily symmetric. That is, a combination of a paragraph in a first document and its most similar paragraph in a second document need not match a combination of that paragraph in the second document and its most similar paragraph in the first document. For example, looking at the document B from the document A, a paragraph of the document B that is the most similar to theparagraph 1 of the document A is theparagraph 3. However, a paragraph of the document A that is the most similar to theparagraph 3 of the document B is theparagraph 3, not theparagraph 1. In addition, a paragraph of the document B that is the most similar to theparagraph 2 of the document A is theparagraph 2. However, a paragraph of the document A that is the most similar to theparagraph 2 of the document B is theparagraph 1, not theparagraph 2. In contrast, looking at the document A from the document B, a paragraph of the document A that is the most similar to theparagraph 1 of the document B is theparagraph 1. In addition, a paragraph of the document A that is the most similar to theparagraph 2 of the document B is also theparagraph 1. However, a paragraph of the document B that is the most similar to theparagraph 1 of the document A is thedocument 3, as has been described above, not theparagraph 1 or theparagraph 2.

Example of Analysis Result Presenting Screen

FIG. 5 is a diagram illustrating an example of an analysis result presenting screen generated by the analysis-result-presenting-screen generating unit150 of the sharedinformation management server100. An analysis result presentingscreen410 is displayed on theoutput apparatus400. The vertices of a graph on the analysisresult presenting screen410 illustrated inFIG. 5 correspond to the documents and paragraphs illustrated inFIG. 4. For example, “DA” of the vertex “DA1” indicates the document A, and “1” indicates theparagraph 1. In addition, the vertices are arranged in groups of documents in the example illustrated inFIG. 5. Note that, in the example illustrated inFIG. 5, each side formed between vertices is merely an example, and does not reflect similarity between paragraphs illustrated inFIG. 4. For example, the vertex “DA1” is connected to the vertex “DB3”, the vertex “DC3”, the vertex “DD2”, and the vertex “DE3”, which are different from the related paragraphs (theparagraph 3 of thedocument 3, theparagraph 2 of the document C, theparagraph 2 of the document D, and theparagraph 1 of the document E) of theparagraph 1 of the document A illustrated with reference toFIG. 4.

BecauseFIG. 5 merely illustrates an example of display of the analysisresult presenting screen410, for the sake of simplicity, the graph is an undirected graph where each side has no direction. Actually, however, as described above, the relation between paragraphs is not symmetric. Thus, the graph on the analysisresult presenting screen410 is created as, for example, a directed graph. In this case, each side is described as an arrow directed from one vertex to another vertex in accordance with the relation between paragraphs. In addition, in the example illustrated inFIG. 5, in the case where the user selects a vertex on the analysis result presenting screen displayed on theoutput apparatus400 by performing an operation such as clicking, the display screen of theoutput apparatus400 is switched to display a paragraph corresponding to the selected vertex.

Example of Determining Target of Sharing Work

FIG. 6 is a diagram illustrating an example in which the target of the sharing work is determined by thefacilitation determining unit220 of theprogress control server200.FIG. 6 illustrates the degree of similarity of each of the related paragraphs with each of theparagraphs 1 to 3 of the documents A to E. For a paragraph of interest, there is only one related paragraph in each document. InFIG. 6, paragraphs are omitted in a document including a related paragraph serving as the target of comparison. The degree of similarity between each of theparagraphs 1 to 3 in each of the documents A to E and each related paragraph, illustrated inFIG. 6, is based on the example illustrated inFIG. 4.

As described above, thefacilitation determining unit220 determines, among related paragraphs, a related paragraph with the lowest degree of similarity as the target of the sharing work. InFIG. 6, when attention is paid to theparagraph 1 of the document A, the degree of similarity with (theparagraph 3 of) the document B is 0.99; the degree of similarity with (theparagraph 2 of) the document C is 0.99; the degree of similarity with (theparagraph 2 of) the document D is 0.88; and the degree of similarity with (theparagraph 1 of) the document E is 0.63. Therefore, because 0.63 is the lowest degree of similarity, theparagraph 1 of the document E serves as the target of the sharing work. Similarly, a related paragraph that serves as the target of the sharing work is determined for each of theparagraph 2 and theparagraph 3 of the document A, theparagraphs 1 to 3 of the document B, theparagraphs 1 to 3 of the document C, theparagraphs 1 to 3 of the document D, and theparagraphs 1 to 3 of the document E.

Determination Information for Related Paragraph Serving as Target of Sharing Work

FIG. 7 is a diagram illustrating an example of determination information for a related paragraph serving as the target of the sharing work. In the example illustrated inFIG. 7, the following items of information are recorded for each related paragraph: the identification information of “document” and “paragraph”, “degree of similarity”, and “number of characters”, “allocated time”, “work time”, and “cumulative time” of the paragraph. “Document” is the identification information of a document including the related paragraph, and “paragraph” is the identification information of the related paragraph. Here, information for identification to be performed by thefacilitation determining unit220 is recorded. “Degree of similarity” is the degree of similarity of the related paragraph. “Number of characters” is the number of characters described in the related paragraph. “Allocated time” is time allocated by thefacilitation determining unit220 for the work of sharing the related paragraph. This “allocated time” is a value calculated on the basis of the number of characters in the related paragraph. Here, the allocated time is calculated on the basis of 60 seconds per 200 characters. “Work time” is time allocated for the related paragraph in order to actually implement the sharing work within the preset work time of the entire sharing work. Because the entire work time is often set in minutes or the like, here, a fraction of the time indicated in “allocated time” is rounded up to a multiple of ten. “Cumulative time” is the accumulated “work time” in order from the top related paragraph. In addition, related paragraphs are arranged from the top in ascending order of degree of similarity. In the case where the work time of the entire sharing work is set to 15 minutes, with reference to “cumulative time” inFIG. 7, if the work of sharing the tenth related paragraph (document E, paragraph 1) is performed, the time exceeds the set time of 900 seconds (15 minutes). Thus, the sharing work is performed up to the ninth related paragraph (document A, paragraph 1).

Example of Facilitation Information Presenting Screen

FIG. 8 is a diagram illustrating an example of a facilitation information presenting screen generated by the facilitation-information-presenting-screen generating unit230. A facilitationinformation presenting screen420 is displayed on theoutput apparatus400. The facilitationinformation presenting screen420 illustrated inFIG. 8 indicates related paragraphs up to the ninth related paragraph of the determination information illustrated inFIG. 7 as the target of the sharing work, which are in the order (work order) of the related paragraphs inFIG. 8. On the facilitationinformation presenting screen420 illustrated inFIG. 8, the following items of information are displayed for the related paragraphs serving as the target of the sharing work: “order of priority”, the identification information of “document”, the identification information of “paragraph”, and “work time”. “Order of priority” is the order of implementing the sharing work, which is determined by thefacilitation determining unit220 on the basis of the degree of similarity of each related paragraph. The identification information of “document” is the identification information of a document including the related paragraph. Unlike the identification information illustrated inFIG. 7, this is information for a user who looks at the facilitationinformation presenting screen420 to identify the document. For example, the document file name or the identification information of a user who is the author of the document is used. Like the identification information of “document”, the identification information of “paragraph” is information for a user who looks at the facilitationinformation presenting screen420 to identify the paragraph. The work time illustrated inFIG. 7 is recorded in “work time”. On the facilitationinformation presenting screen420 illustrated inFIG. 8, if the user selects the row of a related paragraph that serves as the target of the work, the display of theoutput apparatus400 is switched to display the selected related paragraph.

Example of Related Paragraph Displaying Screen

FIG. 9 is a diagram illustrating an example of a related paragraph displaying screen. A relatedparagraph displaying screen430 displayed on theoutput apparatus400 is provided with atarget information field431, a relatedparagraph displaying area432, and button objects433 and434. Thetarget information field431 indicates information for identifying a displayed related paragraph. In the example illustrated inFIG. 9, information described in the item “document” and the item “paragraph” on the facilitation information presenting screen illustrated inFIG. 8 is displayed to identify the document and the paragraph. That is, it is illustrated that theparagraph 1 of the document FX28816 is displayed on the relatedparagraph displaying screen430 illustrated inFIG. 9. Sentences described in the related paragraph are displayed in the relatedparagraph displaying area432.

Thebutton object433 indicated as “completed” is an object for confirming that the work of sharing the related paragraph displayed on the relatedparagraph displaying screen430 has been completed. In response to an operation (clicking the mouse, for example) on thebutton object433, a command for notifying that the sharing work has been completed is output to theprogress control server200. On receipt of the command, theprogress control server200 updates the status of the related paragraph displayed on the relatedparagraph displaying screen430 to details indicating that the sharing work has been completed, and returns the display of theoutput apparatus400 to the facilitationinformation presenting screen420. At this time, on the facilitationinformation presenting screen420, the row of the related paragraph for which the sharing work has been completed is displayed distinguishably from the other related paragraphs by changing the display color of the row, for example.

Thebutton object434 indicated as “return” is an object for returning to the facilitationinformation presenting screen420 without completing the work of sharing the related paragraph displayed on the relatedparagraph displaying screen430. In response to an operation (clicking the mouse, for example) on thebutton object434, a command for ending the display without completing the sharing work is output to theprogress control server200. On receipt of the command, theprogress control server200 returns the display of theoutput apparatus400 to the facilitationinformation presenting screen420 without updating the status of the related paragraph displayed on the relatedparagraph displaying screen430. At this time, the work of sharing the related paragraph displayed on the relatedparagraph displaying screen430 is not completed, and therefore, the display mode of the row of the corresponding related paragraph on the facilitationinformation presenting screen420 is not changed.

The configuration of the analysisresult presenting screen410 illustrated inFIG. 5, the configuration of the facilitationinformation presenting screen420 illustrated inFIG. 8, and the configuration of the relatedparagraph displaying screen430 illustrated inFIG. 9 are all examples, and are not limited to the illustrated configurations as long as they are screens including information and functions required at each stage. For example, although the work time of each related paragraph is presented on the facilitationinformation presenting screen420 illustrated inFIG. 8, alternatively or additionally, the cumulative time illustrated inFIG. 7 may be presented. In the above-described example, the row of a related paragraph for which the sharing work has been completed is distinguishably displayed on the facilitationinformation presenting screen420. In addition, if the time allocated to each related paragraph has elapsed, the corresponding row on the facilitationinformation presenting screen420 may be distinguishably displayed. On the facilitationinformation presenting screen420, a row selectable for displaying the relatedparagraph displaying screen430 may be limited to that in the order indicated in “order of priority”, or a row may be selectable regardless of the order indicated in “order of priority”. Furthermore, selection of the row of a related paragraph for which the sharing work has been completed may be limited.

Although the exemplary embodiment of the present disclosure has been described above, the technical scope of the present disclosure is not limited to the above-described exemplary embodiment. For example, although to-be-shared information is described in the description form500 (seeFIG. 10) and is read by theinput apparatus300 in the above-described exemplary embodiment, a document describing to-be-shared information may be created as an electronic document using a personal computer or another information processing apparatus, and the document may be directly input to the sharedinformation management server100. In addition, various changes or replacements of configurations that do not depart from the scope of the technical idea of the present disclosure are included in the present disclosure.

In the embodiment above, the term “processor” refers to hardware in a broad sense. Examples of the processor include general processors (e.g., CPU: Central Processing Unit), dedicated processors (e.g., GPU: Graphics Processing Unit, ASIC: Application Integrated Circuit, FPGA: Field Programmable Gate Array, and programmable logic device).

In the embodiment above, the term “processor” is broad enough to encompass one processor or plural processors in collaboration which are located physically apart from each other but may work cooperatively. The order of operations of the processor is not limited to one described in the embodiment above, and may be changed.

The foregoing description of the exemplary embodiment of the present disclosure has been provided for the purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure to the precise forms disclosed. Obviously, many modifications and variations will be apparent to practitioners skilled in the art. The embodiment was chosen and described in order to best explain the principles of the disclosure and its practical applications, thereby enabling others skilled in the art to understand the disclosure for various embodiments and with the various modifications as are suited to the particular use contemplated. It is intended that the scope of the disclosure be defined by the following claims and their equivalents.
